1.3
Dispensing system
With feed valves or feed chutes controlled with coarse and fine feed, the dispensing
sample is automatically infed up to the specified target value.
The control signals for the feed valves are transmitted to the 8-690 relay box via the
RS485-690 interface. The 8-690 relay box controls the dispensing system either
directly or via an additional external control unit (PLC). In the case of overloading or
underloading of the weighing platform, all valves are closed immediately.
A maximum of two 8-690 relay boxes can be connected. With a second relay box a
dispensing system with below-level dispensing can be controlled without a PLC
("nozzle control"). The IND690-Fill then assumes the function of a control unit with
the moving of a filling nozzle or the switching of a drip pan and outputs signals to the
nozzle correction, pregasing and postgasing.
The IND690-Fill can be remote controlled with "electronic fingers". These electronic
fingers trigger various keys via interface commands on the terminal, see section 3.
Alternatively to the relay box 8-690 the dispensing system can also be controlled by
using the interface 4I/O-690 and relay box 4-690 or by using ARM100.
Please note that the accuracy of the filling results and the filling speed are not only
dependent on the scale, but also on the other system parts, and in particular on the filling
device itself (valves, feed chutes etc.). Only the optimum co-ordination of all
components with each other produces the best filling results.

Dispensing process
Dispensing is carried out in 5 consecutive steps:
• Automatic tare – Automatic taring of the container and dispensing start
• Coarse feed – Dispensing with coarse feed up to the coarse/fine-feed switch-over
point (limit 1)
• Fine feed – Dispensing with fine feed up to the switch-off point of the fine feed
(limit 2)
• Redispensing correction – Redispensing correction of fine feed beyond limit 2
• Redispensing – If the weight value does not lie within the tolerance of the target
value at the end of dispensing, automatic or manual redispensing up to the target
value
If not limits are entered, the IND690-Fill automatically determines Limit 1 and Limit 2
in a learn mode, see page 20. The target weight is then exactly reached already
during the first dispensing.
To optimize the dispensing process, Limit 2 is automatically adjusted with the same
component during the next dispensing process, see REDISP. CORRECTION block on
page 16.
If the container is underfilled, manual or automatic redispensing can be carried out
depending on the settings in the master mode.

Dispensing
The dispensing type is dependent on the application set in the master mode:
• ABOVE LEVEL: Dispensing above the filling level (without filling lance)
• BELOW LEVEL Dispensing lance below the dispensing level
The filling process is not started unless the dispensing lance is recognised in the
right position, meaning that the input signal NOZZLE DOWN has to be active.
• BELOW BUNGHOLE Dispensing lance below the bung hole
The filling process is not started unless the dispensing lance is recognised in the
right position, meaning that the input signal NOZZLE MIDDLE has to be active.

Dispensing functions
IND690-Fill
Notes
• For the application BELOW LEVEL/BELOW BUNGHOLE, NOZZLE CONTROL ON two
8-690 relay boxes must be connected.
• During the filling process exactly one of the signals NOZZLE DOWN / MIDDLE / UP
has to be active. Otherwise the error message SEVERAL INPUTS ON or WAITING
FOR INPUT is displayed. The filling process is not continued until exactly one of
these signals is active.
• A new filling process can only be started if the input signal NOZZLE UP has been
recognised beforehand.
• For sequence charts of the individual applications, see section 6.2.

REDISP. CORRECTION
Switch redispensing correction on or off
The redispensing correction function optimizes the switch-off point of the fine feed
(limit 2).
If REDISP. CORRECTION ON is set, the target-actual difference is determined for
each container and multiplied by a FACTOR.
Target-actual difference x correction factor = Δ
Limit 2 is automatically corrected by the value Δ when dispensing the next
container:
Example: For a target-actual difference of 10 g and a factor of 0.5, limit 2 is
corrected by 5 g.
Factory setting: REDISP. CORRECTION ON
FACTOR
Correction factor by which the target-actual difference is multiplied. The result is the
value Δ by which limit 2 is corrected.
Possible values: 0.1 … 0.9 (factory setting: 0.5)
CORREC. THRESHOLD
The correction threshold specifies the target-actual difference up to which the
redispensing correction corrects limit 2.
• Possible values: O … 99 in multiples of the tolerance
(Factory setting: 0, i. e. limit 2 is corrected for all actual values)
• Limit 2 is not corrected when TOTALIZING ON is set and after at least 10
consecutive dispensings the actual value lies outside the correction threshold for
the first time. This value is considered a freak value. If during the next dispensing
the actual value lies outside the correction threshold, limit 2 is automatically
corrected. If in the process limit 2 ≤ limit 1, then the learn mode is automatically
activated.

MONITOR DISPENSING
Switch monitor dispensing on or off
Example
Big bag emptying
If SUBTRACTIVE WEIGHING ON is selected, the dispensing monitor stops the
emptying process as soon as the big bag is fully emptied. The last filling process is
generally not yet complete here. The previously removed weight can be saved by
pressing the TARE key. After inserting a new big bag and pressing the START key,
the interrupted filling process is then completed.
Practical example
A big bag with 2,000 kg of bulk material is to be filled into sacks of 300 kg each.
• IND690-Fill performs six filling processes (1,800 kg filled).
• With the seventh filling process, only 200 kg can be filled. The dispensing
monitor stops the filling process.
• Press the TARE key to save the 200 kg already filled.
• Insert a new big bag and press the START key.
• The seventh sack is topped up to the required 300 kg.
ACKNOWLEDGE
Switch acknowledgement of the next dispensing process on or off
After completing one dispensing process, the next dispensing process can be
started with or without acknowledgement.
Acknowledgement is triggered with the following actions:
• Weight change > 30 digit
• Pressing the START key
• Interface command {A[W|3[5[2|_|1} or {A[W|3[0[6|_|$|$|9}, see
section
• Signal at input IN 4 of the first 8-690 relay box
ACKNOWLEDGE ON
Moving the weighing platform by at least 30 digit or pressing the START key in the
DISPENSING OKAY state results in the READY FOR DISPENSING state.
The next dispensing process is started with the START key (factory setting).
ACKNOWLEDGE OFF
After the dispensing process is completed and the START is pressed, the next
dispensing process is started immediately. READY FOR DISPENSING is not
displayed.
COARSE FEED

and change run automatically.
To prevent valves from opening when no container is on the scale, the tare
monitoring function must be used in this setting.
Separate dispensing parameters can be entered for both weighing platforms. This
enables the control of two dispensing systems. For weighing platform 1 the
dispensing parameters must be saved to target memory 1, and for weighing
platform 2 to target memory 2.
If the same dispensing parameters are to be used for dispensing on both weighing
platforms, target memory 1 and 2 may not be assigned.
SUBTRACTIVE
WEIGH.
This function enables the quasi continuous dispensing from two supply vessels
standing on weighing platforms 1 and 2.
If the entered gross weight value WEIGHT is dropped below, the valves are closed,
the stabilization of the weighing platform is waited for and the other weighing
platform selected. The interrupted dispensing process is ended from the second
container.
With this alternative only one parameter set can be used.
Comments
• Output OUT2 shows which weighing platform is currently active during the
dispensing process: LOW = weighing platform 1, HIGH = weighing platform 2.
• The correct weighing platform number automatically appears on the printout.
• The weight value WEIGHT required during WEIGHING OUT is available in the
